B2G Crypto Asset Recovery Platform

Crypto custody solutions for government agencies presented unique challenges. We served as the founding engineering team for a UK-based B2G platform that enables law enforcement to identify, seize, custody, and legally process criminal cryptocurrency. The work remains confidential due to national security considerations, but we are proud to have built the foundation.

The Challenge

Government agencies faced a growing problem: criminal organizations were using cryptocurrency to launder money, fund illegal operations, and hide assets from seizure. Traditional asset recovery processes couldn't handle digital currencies. Law enforcement needed technology that could keep pace with sophisticated criminal use of blockchain.

The requirement was clear: build an end-to-end platform that takes seized cryptocurrency from identification through legal processing, with security and documentation standards for criminal prosecutions.

Asset Identification

Government agencies needed to trace and identify cryptocurrency held by criminal entities across multiple blockchains and wallet types.

Legal Seizure Process

The platform had to support court-ordered seizures with proper chain of custody documentation that would hold up in legal proceedings.

Secure Custody

Once seized, criminal assets required custody infrastructure that met national security standards with zero tolerance for loss or compromise.

Regulatory Coordination

Multiple government agencies needed controlled access to seized assets while maintaining separation of duties and audit compliance.

What We Built

An end-to-end crypto custody solution that handles the complete lifecycle of seized criminal cryptocurrency.

Multi-Chain Asset Discovery

Built systems to identify and track cryptocurrency across Bitcoin, Ethereum, and other major blockchains. Address clustering, transaction tracing, and wallet fingerprinting.

Seizure Workflow Engine

Automated the legal seizure process from court order to asset transfer. Document generation, approval chains, and timestamped evidence collection.

HSM-Backed Custody

Hardware Security Module integration for tamper-proof key storage. Multi-signature schemes requiring authorized personnel from multiple agencies.

Evidence-Grade Audit Trails

Immutable logging of every operation with cryptographic attestation. Chain of custody records designed to satisfy court requirements.

Security Requirements

National security standards left no room for compromise. Every architecture decision prioritized security over convenience.

National Security Clearance

Systems built to standards required for handling sensitive government operations and classified intelligence data.

Air-Gapped Cold Storage

Offline key storage with multi-party signing ceremonies. Geographic distribution of backup materials.

Role-Based Access Control

Fine-grained permissions ensuring proper separation between investigating officers, custodians, and legal personnel.

Penetration Testing

Extensive security audits conducted by government-approved third parties before deployment.

Our Role as
Founding Engineers

Hexmount wasn't brought in to extend existing technology. We were part of the founding engineering team that built this platform from the ground up. From initial architecture decisions to deployment, we shaped the technical foundation.

This wasn't a vendor relationship. We embedded with the team, operated as internal engineers, and took ownership of critical systems. The crypto custody solutions we built had to work the first time. No margin for error when handling evidence in criminal proceedings.

The experience shaped how we approach every security-critical project. Standards that satisfy government agencies inform all our institutional work now.

Status Today

The platform remains in active use. We have since stepped back due to the sensitive nature of the work.

We're proud to have contributed to this platform. The sensitive nature of the work means we can't share client details or technical specifics. What we can share is that this experience shaped our approach to crypto custody solutions and institutional blockchain development.
